Description

Eucalyptus longissima is a mallee that typically grows to a height of 8 m (26 ft) and forms a lignotuber. It has smooth greyish brown bark, usually with rough, fibrous or stringy bark on most of the trunk. The adult leaves are lance-shaped, 55–110 mm (2.2–4.3 in) long, 7–16 mm (0.28–0.63 in) wide on a petiole 10–20 mm (0.39–0.79 in) long. The flower buds are arranged in groups of between seven and fifteen in leaf axils on an unbranched peduncle 7–17 mm (0.28–0.67 in) long, the individual buds on pedicels 3–7 mm (0.12–0.28 in) long. Mature buds are narrow oval to spindle-shaped, 7–12 mm (0.28–0.47 in) long, 2–6 mm (0.079–0.236 in) wide with a conical to horn-shaped operculum 4–9 mm (0.16–0.35 in) long. Flowering has been observed in most months and the flowers are white. The fruit is a woody, shortened spherical capsule 4–6 mm (0.16–0.24 in) long and wide. [2] [3]

Taxonomy and naming

Eucalyptus longissima was first formally described in 2005 by Dean Nicolle in Australian Systematic Botany . [4] The specific epithet (longissima) is the superlative form of the Latin word longus, hence "longest", referring to the juvenile leaves, peduncles and pedicels. [5]

Distribution and habitat

This eucalypt grows in sand or loam over limestone in the Coolgardie, Great Victoria Desert, Murchison and Yalgoo biogeographic regions of Western Australia. [3]

Conservation status

This eucalypt is classified as "not threatened" in Western Australia by the Western Australian Government Department of Parks and Wildlife. [3]
